For Hospital Use Only Pigeon 100ml Glass Bottle Set of 2 Ships Today These bottles were purchased at the hospital. They were used to supplement breastfeeding with a small amount of formula, so they weren't used very often. Above all, they have few parts, which was a lifesaver for my second child and during nighttime feedings. The nipples are discolored because they were sterilized after each use. Please consider them as a bonus. Please let me know if you don't need them. - Brand: Pigeon - Quantity: Set of 2 - Material: Glass - Capacity: 100ml - Graduations: Yes Thank you for looking.
